What are spring steel washers used for and what is the purpose of a spring washer
Spring washers are tiny pieces of metals that are designed to do big jobs. They are round in shape with a hole in the middle. They are meant to be used with fasteners to spread their load onto a wider surface and prevent them from loosening.
The steel washers are placed between the bolt head/nut and the mating surface to create axial flexibility. They are used in almost every industry ranging from building & construction to automotive and aerospace. They are designed to perform big jobs.
